F.E.M. ANALYSIS ABOUT THE INFLUENCE OF THE BURNING CHAMBER ON THE ENGINE POWER AT D.I. DIESEL ENGINE

The performance and emission characteristics of the Diesel engine depend on the geometry of the combustion chamber and the definition of fuel-injection parameters as well as the previous described charge motion design. A numerical tool incorporated into the development process, as well as the COSMOS/M program, gives the opportunity for the optimization of the combustion and injection processes and diagnosis of test bench results are playing an increasingly important role. It is now possible to closely model the complex interactions between highly turbulent flow processes as well as the interactions between multi-phase flow and combustion processes.
